1 Claim.

(Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) The present invention relates to ring clamps for installing clutch shaft flange ring on a clutch shaft flange.

In the past, the installation of clutch shaft flange rings on a clutch shaft has been a slow and tedious task, often resulting in the installation of seriously distorted and damaged rings.

It is an object of the present, invention to provide a spring clamp for use in assemblin flange rings on a clutch shaft flange.

Another object of the present invention is the provision of a spring clamp with element engaging means.

A still further object of the present invention is the provision of a spring clamp that will hold a ring firmly in place during assembly.

Other objects and advantages of the invention will become apparent during the course of the following detailed description, taken in connection with the accompanying drawing, forming a part of this specification, and in which drawing:

Fig. 1 is a front elevational view of a spring clamp, illustrating the configuration of the clamp and the gripping means.

Fig. 2 is an end, elevational view of Fig. 1.

Fig. 3 is an elevational view of a clutch shaft and flange and illustrating the spring clamp holding a ring on the shaft flange, the ring being shown in section and parts being shown fragmentarily.

Referring to the drawings the numeral Ill represents a spring clamp of spring strip material framed or bent into approximately a spiral configuration, one end ll of the strip being looped inwardly, the opposite end l2 extending outwardly and beyond the end I I. The end I I is provided with a pair of gripping fingers l3 that are bent at an angle to the strip [0, the fingers being on each edge of the strip. Between the fingers I3 is a tongue [4 that extends outwardly beyond the gripping fingers forming an element engaging means.

In Fig. 3 of the drawings there is illustrated the present device in use, and in this showin the numeral l5 represents a clutch shaft that is shown fragmentarily. The shaft l5 rcarries pinion gears I6 and I1,a clutch plate [8, a flange l9 and a hub 20. Encircling the flange I9 is a clutch 2 shaft flange ring 2|. The ring 2! is held impinged on the peripheral wall of the flange l9 by the fingers IS the top face of the tongue l4 engaging the bottom portion of the flange ring 2!. The end ll. of the spring clamp engages the bottom face of the clutch plate l8 forming a gripping means. From the above it can be seen that the clutch shaft flange ring is held firmly in place during assembly of other parts, and that damage to the 10 ring during assembly is prevented.

The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties l5 thereon or therefor.

What I claim is:

A clamping device for positioning a ring on the hub of a shaft flange comprising a, spiral-like resilient strip one end of which extends beyond and overlaps the other end, a pair of spaced fingers integral with and extending outwardly at approximately right angles to surface of the strip at said one end, a tongue integral with and extending forwardly from said one end, said tongue extending from a position between said fingers and the said other end of the strip extending inwardly of said spiral-like resilient strip whereby, when said clamping device is placed radiall over the edge of said flange to position a ring on said hub the tongue projects between the ring and the flange and said fingers bear upon the outside periphery of said ring, the said device holdin the ring in position on said hub by frictional engagement with said flange.
